    Make sure the motor is running free. If the bearings are going bad it can stall the motor. That would put extra load on the capacitor and caus it to overheat. Also make sure your getting full voltage at the motor. If you have a clamp on amp gauge then check the amps for both start up and running of the motor.

    Time for a new motor and a matching new capacitor. Once they are smoked and overheated they are toast.
